I've been doing some animation in Poser, and so far so good....I am guessing because I learned on my own that I am missing something but anyway....is there a way to adjust a body part, then a few frames later adjust the bodypart to a different place without having the entire timeline change? I mean without having to go frame by frame. 

The main issue I am having is that I'll want them to blink or shrug or lift a arm up for a moment. I get to the first part of that animation just fine but by setting the second keyframe it messes up the rest of the frames. 

If anyone can help that would be appriciated :)
